Bragg's Law For Diffraction
The Terms
- Spacing between planes in the atomic lattice [Units: m]
- Angle between the incident wave and the scattering planes
- An integer determined by the order
- Wavelength of the incident wave [Units: m]
What Does It Mean
In crystallography, this equation is used to find the angles of coherent and incoherent scattering off a crystal lattice. For direction in which the above equation is satisfied, waves scattered from atomic planes separated by a distance interfere constructively and produce maxima on the diffraction pattern.
